Current loop output

5.3.1 P08 Manual output current value
FACTORY DEFAULT: 4.0
If the analog current loop output mode (P12b) is set to "Manual," the output current takes the value specified here, and the analog
transmission switches off. A value between 3.8...20.5 mA is specified in this parameter. Caution! The device automatically switches
to "Manual" current output mode when a new value is set in parameter P08. When 0 is entered, the device switches to "Automatic"
current transmission mode (P12b = 0) and resets the value of parameter P08 to the factory setting.
In HART multi-drop mode (see parameter P19), the current loop output is fixed at 4 mA, as per standard, and the manual output
current value (P08) does not apply.

5.3.2 P10 The value of the transmitted quantity assigned to 4 mA output current
FACTORY DEFAULT: 0.0
In the case of "Automatic" mode of the analog current output, it is the PV value assigned to 4 mA (usually the lower limit of the measu-
ring range in the case of level measurement). The device scales the (HART – PV, see P01) output value to the analog current output
4...20 mA range using the values specified in parameters P10 and P11.

5.3.3 P11 The value of the transmitted quantity assigned to 20 mA output current
FACTORY DEFAULT: Xmax (See table of P03)
In the case of "Automatic" (current transmission) mode of the analog current output, it is the PV assigned to 20 mA (usually the upper
limit of the measurement range in the case of level measurement). The device scales the (HART – PV, see P01) output value to the
analog current output 4...20 mA range using the values specified in parameters P10 and P11. The values can be assigned inversely.
(For example, 4 mA to 1 m [3.3 ft] level and 20 mA to 10 m [33 ft] level, or vice versa 20 mA to 1 m [3.3 ft] level and 4 mA to 10 m [33
ft] level.)
